China's devaluation of the yuan Tuesday surprised global markets and left analysts wondering what it might mean. Leaders in Beijing are probably asking themselves the same thing.

China's monetary authorities cut the currency's value against the dollar by 1.9 percent, the biggest move in years. Was this a liberalization of the country's system for managing the yuan, a step to stimulate China's flagging economy, or the beginning of a currency war? Mostly, it was a combination of the first two -- but the question now is how authorities will strike this balance between pro-market reform and pro-export stimulus.
